SPLICING CLIP.

Application filed December 20, 1921.

To all whom it may concern: I

Be it known that I, CHARLES LEA, a cit izen of the United States, and resident of Boston, in the count-y of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Splicing Clips, of which the following is a specification.

This invention relates to binding clips and is more especially intended for use in splicing together sets of warp threads in weaving.

In practice it has been customary to tie the ends of two sets of warp threads together, but oftentimes the tying knots form an obstruction which interferes with the easy passage of the threads through the eyes of the harness or otl'ier parts of the apparatus. Vhile it has been proposed to unite the warp threads by means of binding clips instead of tying, yet in order to make this method c-on'nnercially feasible it is necessary to use a clip capable of rapid and economical application to the warp threads and so constructed as to present no substantial obstruction to the passage of the united threads through the harness or reed and to allow clips of the same size to be used to unite a greater or less bulk of warp threads with equal security.

It is a characteristic feature of the present invention that the fastening members of the clip can be clinched upon the warp threads with a greater or less degree of over-lapping of their free ends without superimposing one fastening member above the other, which would result in givingtwo thicknesses of metal outside the united threads, thus producing an objectionably large obstruction at that point.

Another feature of the present construction consists in the adaptability of the clip to being manufactured in continuous strips so arranged as to be rapidly and accurately fed into a splicing machine constructed to Sever the individual clips and clinch them around the threads to be united.

In the accompanying drawings I have illustrated a preferred form embodying the principles of this invention, in which,

Figure 1 is a side elevation of a series of clips formed in a continuous strip.

Figure 2 is an end elevation of such strip.

F gure 3 illustrates the method by which the strip may be fed through the severing and splicing machine.

Serial No. 523,751.

Figure at is a. plan View showing a single clip clinched to enclose and hold two overlapping tuft-s of warp threads.

Figures 5, 6 and 7 show the same size clips in clinched position about a progressively decreasing number of strands or threads, thereby illustrating the range of capacity of clips having this construction.

Figure 8 shows an individual clip in open or unclinched position.

The individual clip itself in its preferred form for use is of U-shape transversely. One of its sides is notched inwardly from its edges to form a pair of tongues or prongs a separated by the notch, while the other side is formed into a single prong or tongue a whose apex or free end lies directly opposite the space. or notch between the pair of prongs a sothat when the prongs are any obstruction or projection likely to catch against the reeds or harness through which the united threads are drawn.

Furthermore, this construct-ion results in adapting clips of uniform size to be used to encircle a. greater or less bulk of threads, since the considerable circumferential overlapping of the prongs a in relation to the prongs (4 allows very substantial variation in the diameter or size of the eye formed by the clip when clinched. This variation in capacity is illustrated in Figures 1, 5, 6 and 7.

This form-of clip is readily adapted to be manufactured in continuous strips, as shown in Figure 1. Each side of the metallic blank or strip is provided with two series of notches, one series of notches cl being formed to receive the opposite tongue or pron'g a, while the other series of notches d, which may be termed severing notches, serve to form a partial severance of the individual clips in the strip from one another, the severing operation being made by a suitable punch in the splicing machine. It will be noticed also that the severin'g notches on each side are opposite each other, while the prong neceiving notches are transversely off-set, the-two sets; of notches on each side alternating with each other. The obj eat of this particular arrangement is to, facilitate the accurateand positive feeding otf'thestrip into the splicing machine by a feed Wheel 6, which, as shown in Figure 3, has foun-teetht e on one side of its central hub 6 arranged in alternation circumferentially with, four. similar teeth 6 on the opposite side, so that each successive tooth e, e of. the feed Wheel during its, intermittent: rotation. will: engage a severing notch in\ alternation, on either side oitthe. feed strip:

The continuous back; of; the strip is severablenanrioss from one severing on tooth engaging notch; to, the opposite severing notch, thus forming; single or individual clip having on, onefside a tongue receiving recess bounded by a pair: of separate prongs, andat; the other side-a tongnefatth-e middle portion of: the clip-.opposite said: tongue re ceivin-grecess, and; adaptedto be folded or bent; ingtosaiidn'ecess. In the open position before setting, the, clip ihasno obstruction to the, easy introductionof the c-ordsor.threads to, be unitediwhilethe setting operation brings. theentire blacle or body pertien of the. clip aswell as-the illlIiBG-Ofi-S'Qil prongsinto tight: engagement; with. the encircled threads-,; since by means-roti'aisimple setting die, and 1 anvil, the prongs may be forced by each other? and tightly clinched around 1 the threadsso-as to formapra-ctica-lly complete tube tightlya imbedded! in. the bodyof the threadsso that :the presence-of theel-i p forms not enlargement; or: projeetion beyond the surfaceof the: united thfreads.
